Question

What is the number of moles in 92.5 grams of titanium?

A) 0.924 moles
B) 1.500 moles
C) 1.934 moles
D) 2.542 moles

Answer 1

The number of moles in 92.5 grams of titanium is calculated by dividing the mass by the molar mass of titanium, which is 47.867 g/mol. The result is approximately 1.934 moles, hence the correct answer is C) 1.934 moles.

Step-by-step explanation:

The number of moles in 92.5 grams of titanium is determined by using the molar mass of titanium. To find the number of moles, you divide the mass of the titanium sample by its molar mass. The molar mass of titanium is 47.867 g/mol.

1. Calculate moles of titanium: moles = mass (g) / molar mass (g/mol).
2. Divide 92.5 g by 47.867 g/mol to get the number of moles.
3. 92.5 g / 47.867 g/mol = 1.934 moles.

The correct answer is C) 1.934 moles.
